Product introduction
Rotating Electromagnet, the magnetic field can be rotated 360° around the axis of rotation, can be equipped with a stepper motor to control the rotation of the magnet accurately, arbitrarily set the rotation angle, and programmable control forward rotation and travel time. The controller's angular resolution is 0.01 degrees, the mechanical step angle is 0.1 degrees, and the repeatability is 0.05 degrees.

3. Testing environment |
|||
|
The detection environment is closer to the actual environmental conditions used by the user, including factors such as lead wire length and ambient temperature. The time is selected in the time interval where the fluctuation of the geomagnetic field is small. Before the test, the instruments required for the test were turned on and warmed up in advance and the measurement environment was recorded, as shown in Table 1. |
